Geometric dependence of critical-current variation in Al/AlO/Al Josephson junctions: a model-based analysis
K. Kakuyanagi, N. Teran, H. Toida +1
Achieving uniform critical current across Josephson junctions is essential for the large-scale integration of superconducting quantum circuits. In this work, we statistically analy…

Identifying impurities in a silicon substrate by using a superconducting flux qubit
Hiraku Toida, Kosuke Kakuyanagi, Leonid V. Abdurakhimov +3
A bismuth-doped silicon substrate was analyzed by using a magnetometer based on a superconducting flux qubit. The temperature dependence of the magnetization indicates that the sil…
